How can I handle timeouts in C# applications?

You can handle timeouts in C# using the CancellationToken or by setting a timeout on tasks. Would you like an example?

Yes, please provide an example using CancellationToken.

Sure! Here's a simple example:

using System;
using System.Threading;
using System.Threading.Tasks;

class Program
{
    static async Task Main()
    {
        var cts = new CancellationTokenSource();
        cts.CancelAfter(2000); // Set timeout to 2 seconds

        try
        {
            await Task.Run(() => LongRunningOperation(cts.Token), cts.Token);
        }
        catch (OperationCanceledException)
        {
            Console.WriteLine("Operation was canceled due to timeout.");
        }
    }

    static void LongRunningOperation(CancellationToken token)
    {
        for (int i = 0; i < 10; i++)
        {
            token.ThrowIfCancellationRequested();
            Thread.Sleep(1000); // Simulate work
            Console.WriteLine("Working...");
        }
    }
}

What if I want to handle timeouts for an HTTP request?

For HTTP requests, you can set a timeout on the HttpClient. Here's an example:

using System;
using System.Net.Http;
using System.Threading.Tasks;

class Program
{
    static async Task Main()
    {
        using var client = new HttpClient();
        client.Timeout = TimeSpan.FromSeconds(5); // Set timeout to 5 seconds

        try
        {
            var response = await client.GetAsync("https://example.com");
            response.EnsureSuccessStatusCode();
            Console.WriteLine("Request succeeded.");
        }
        catch (TaskCanceledException)
        {
            Console.WriteLine("Request timed out.");
        }
    }
}
